XSSI printenv directive
XSSI variables are set in a couple of different ways. You can set your own with
the set command, or you can use one of the variables
that is set automatically for each browser when it requests a page. To see the
list for a specific browser, you can use the printenv command, which
outputs a list of what are called environment
variables for your specific case. The output of printenv looks
like this:
HTTP_USER_AGENT = Mozilla/4.0
[en] (WinNT; I)
The first part (in uppercase) is
the name of the variable. The second part (after the equals sign) is its value.
Basic syntax:
<!--#printenv -->
How to insert a new printenv
directive
To add a printenv directive at
the cursor's current location in your document, either choose "XSSI printenv"
from the Insert menu or click the
icon in the XSSI category on the floating Object palette. If
you have automatic translation enabled (or you
manually translate your document), the appropriate
value will be shown. Otherwise, an icon ()
will appear to show you that there is an invisible element on your page.
The printenv inspector doesn't give
you many options because there isn't anything to specify for printenv. The directive
just outputs all known environment variables. To set new values for the environment
variables (so you can set up a test environment), click on the "Edit
Environment Variables" button.
Since printenv prints out variables
one per line, it is suggested you use the directive between <pre> tags
for readibility.
